aalyn [17]

Answer: Step 2

Step-by-step explanation:

The scale factor is defined as image/preimage, so since the image is circle F and the preimage is circle E, k should be equal to (radius of F)/(radius of E), or 1/2, not 2.

3 feet of snow fell in 1 2/3 hours. What was that rate in inches per hours?
dalvyx [7]

Answer:

21 \frac{3}{5}in/hr

Step-by-step explanation:

Distance of snow fall  = 3ft

Time taken  = 1\frac{2}{3}hrs

Unknown:

Rate of snowfall = ?

Solution:

The rate of the snowfall is the same as the speed of the fall;

  Rate of snowfall  = \frac{distance of snowfall}{time}

Convert the ft to inches;

             1ft  = 12inches

             3ft  = 3 x 12  = 36inches

Input the parameters and solve;

           Rate of snowfall  = \frac{36}{\frac{5}{3} }   = 36 x \frac{3}{5} = 21 \frac{3}{5}in/hr
